PS1 DVD Logo Demo is a small demo for the PlayStation 1 console. It essentially demonstrates the following features/functionality:
Bounces a large 128x74 DVD logo sprite around a screen (of 320x240p resolution) at 60 FPS.
The DVD logo sprite can randomly change to 1 of 7 different colors each time the logo bounces off of the screen and changes direction.
When an exact symmetrical corner hit occurs, an ‘exact corner hit counter’ will appear at the top of the screen after a very brief screen flash of white, as well as a message explaining the controls to dismiss said message. Press DPAD-UP on a controller to dismiss it until the next exact symmetrical corner hit occurs, or press DPAD-DOWN to dismiss it forever. The message explaining the controls will automatically disappear in about 30 seconds after first being displayed if you do nothing. If you do press up or down on your controller, the message explaining the controls will disappear along with the ‘exact corner hit counter’.
PS1 DVD Player uses 7 different CLUTs (ColorLookUpTables) to change the appearance of the single DVD logo sprite, using barely any VRAM. This demo also does not use the libgs library, making it “more to the metal” and tiny in size. The HBlank root counter is used to seed the random function for selecting each CLUT/color on screen.
